IMPROVEMENT IN PNEUMATIC LIQUID-ELEVATORS.

Specification tbrming part of Letters Patent No. 104,301, dated June 14,1870.

To all whom it may concern Re it known that I, JOHN P. GRUBER, of NewYork city, in the county and State of New York, have invented a new andImproved Hydro-Pneumatic Elevator for Raising NVine and other. Liquors;and I do herebydeclare that the` following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawing,making part of this speciiication, in which- Figure 1, Plate 1, is aperspective view oi" the improvedapparatus. Fig. 2, Plate 2, is avertical section through the apparatus, with several of thecommunicating pipes arranged so as to show them in this section. Fig. 3,Plate 2, is a sectional view of the switch-cocks detached from thebodyof the apparatus.

Similar letters of reference indicate corresponding parts in the severalfigures.

The object of this invention is to utilize the force or pressure of ahead of water-such, for instance7 as may be desired from reservoirs usedto supply cities and towns with waterfor the purpose of elevating wineand other liquors from cellars or vaults to upper stories of buildings.

The nature of my invention consists in an apparatus, hereinafterdescribed, whereby air is forcibly expelled from two chambers through asingle pipe by alternately allowing water to enter and escape from thechambers, as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I willdescribe its construe tion and operation.

In the accompanying drawing, A A1 represent two vessels, which are madeof suitable strength to sustain the degree of pressure to which they aresubjected. For convenience these vessels are connected together, oneabove y the other, by means of an intermediate cylindrical case, B, theinterior of which shouldbe in free communication with the external air.

a represents an induction water-pipe, which should be connected to apipe communicating with a head or reservoir of water. This pipe (t isapplied to a valve-box, P, which communica-tes with the interior ofvessel A1 by means of a connection, Gr, and also with the vessel A1 bymeans of a pipe, N. The valve-box P is provided with an oscillatingtwo-way cock, b, having an arm, c, applied to its stem.

In Fig. 2 cock b is turned so as to cut off communication from thevesselA1 and allow water to enter vessel A through the pipe N. Below thepipe e is a water-eduction pipe, e, which is applied to a valve-box, P',which cornmunicates with the vessel A1 at its bottom by means of a pipe,G. Valve-box Il is provided with an oscillating two-way valve, b',having an arm, c', applied fast to its stem. The arms c and c' arepivotedto a rod, T, which is used for operating both valves b b at thesame time for changing the direction ot' the currents, as will behereinafter explained.

In Fig. 2 valve b is represented `in position for cutting 0E the escapeof water from the vessel A by way of pipe B', and allowing water toescape through pipe a from vessel A1 by way of pipe G. The upper vessel,A, isfpro; vided at its top with an air-inlet valve, s, which valve willprevent the escape of air through it. Vessel A is also provided at itstop with a valve-box, D, containing an air-valve, c, which closesdownwardly upon its seat; also, with a valve, j', which closes upwardlyagainst its seat, and which is applied to a vertically-movable stemhaving a ioat, F, on its lower end. When water rises above a givenheight in ves sel A the valve f will be buoyed up by oat F, and byclosing the outlet-passage into pipe A2 prevent farther entrance ofwater into the vessel A.

The pipe B is intended for conducting oit' the water from vessel A,through valve b and pipe a', during the introduction of water 'intovessel A1. The pipe A2, which leads out of valve-box D of vessel A, andalso out of the valve-box D of vessel A1, communicates with a commonair-pipe by means of the branch pipe O.

The vessel A1 is provided at its top with an air-inlet valve, s', which,like valve s, will prevent the escape of air through it. A valve-box,D', is also applied to vessel A1, and provided with two valves, c f',and a float, F', which operate precisely like corresponding partsapplied to valve-box D, and above de-l scribed. G is the water-outletpipe for vessel A1, and is in direct communication with outlet-pipe cwhen valve b is adjusted as shown in Fig. 2. Air will enter the case Bthrough a space left around the air branch of the valvebox D.

Operation.

By depressing the rod T valves b b' will be adjusted as shown in Fig. 2.Valve b will cut oft' communication between vessel Al and inlet-pipe aand open a communication between pipe a and vessel A through pipe N.Water will then low into v'essel A and out through the valve-box D intopipe A2 and close valve c' in valve-box D'. From pipe A2 the air willescape through pipe C. While this is taking place water will be allowedto escape from ves sel A1 through pipes Gr' and a', and this vessel willjill with air, entering it through valve s'. The rod T being raisedvalves b b' will be adjusted as shown in Fig. 3, when the inflow ofwater will be cut oft from vessel A and the iniiow established intovessel A1. At the same time valve b' will prevent the escape of waterfrom vessel A1, but allow its escape from Vessel A through pipes B' anda'. 'Vhile the vessel A1 is being filled with water and its air forcedout through pipe A2, (valve c being shut,) the vessel A will be fillingwith air and its water escaping through pipes B' and a'.

The float-valves f f' are safety-valves to prevent water from rising sohigh in either one of the vessels A A1 as to enter the air-outlet pipeA2.

In practice I shall arrange the apparatus in a cellar or vaultcontaining the liquor to be raised.

The rod T will have a weight or spring applied to it for drawing it downto the position indica-ted in Fig. 2, and by means of a wire or ropecarried up to the apartment into which it is desired to elevate theliquor. The rod T can be raised, as indicated in Fig. 3.

A flexible pipe is applied to the air-branch C, and made to communicate,in. a suitable manner, with a barrel from which it is desired to forceliquor to an upper story. From such barrel a pipe is carried up, andthrough this pipe the liquor is forced by the introduction ot' air intothe barrel from the apparatus.

Having described iny invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of the vessels A A1, two-way cocks b b', passages GG' N B', inlet air-passages s s', and valved outlet air chainbers orpassages D D', substantially as and for the purpose herein described.

2. The combination of the iioats and valves F F fj" with the vessels AA1, cocks b b', passages s s', valved outlet air-passages D D', and pipeA2 C, substantially as described.

3. The arrangement of the two-way cocks b b', links c c', rod T, pipesB' N, and inletvalves s s', applied to chambers A Al, which are providedwith air-outlet passages, substantially as and for the purposedescribed.
